Zynga exec exodus continues as gaming company loses infrastructure CTO

Allan Leinwand, chief technology officer of infrastructure for San Francisco-based social games company Zynga (s ZNGA), has left the company, according to an update on his LinkedIn profile page. Leinwand is assuming a similar role at ServiceNow (S NOW), a company that offers software to automate enterprise IT operations as a service.

Leinwand was once a venture partner at Panorama Capital and founded Vyatta, an open source networking company. He was also the CTO of Digital Island, a content delivery network and CEO of Proficient Networks. Leinwand was one of the key people behind Zynga’s shift away from Amazon’s cloud service to Zynga’s homegrown Z-cloud.

Zynga has been losing senior executives at an alarming rate. Earlier this summer, the company lost about seven executives including Mike Verdu, Zynga’s former chief creative officer and Bill Mooney, who spearheaded the Farmville franchise. Zynga went public at $10 a share and hit an all time high of $14.69 a share in March 2012, but since then has been in a swoon. At close of trading on Friday, Zynga stock stood at $2.88 a share, giving company a market capitalization of $2.19 billion.
